More Trouble For Opportunity's Robotic Arm
Pasadena CA (SPX) Apr 25, 2008A small motor in the robotic arm of NASA's Mars Exploration Rover Opportunity that began stalling occasionally more than two years ago has become more troublesome recently. Rover engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are diagnosing why the motor, one of five in the robotic arm, stalled on April 14 after much less motion that day than in the case of several earlier stal ... more Spirit Still Sitting Pretty For This Time Of Year 
Pasadena CA (JPL) Apr 23, 2008Despite a slight increase in atmospheric opacity caused by dust, Spirit is still enjoying higher-than-expected energy levels for this time of year. Solar array input has been approximately 240 watt-hours per Martian day, or sol (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Clear skies have had the unfavorable effect, however, of causing a drop in ... more Driving on Mars Is Hard 
Pasadena CA (JPL) Apr 23, 2008This week Opportunity demonstrated the challenges of operating a vehicle on the surface of another planet. The rover is en route to Cape Verde to acquire high-resolution images of the layering in the rocks. To get there, Opportunity must cross some sandy stretches. Before entering the sandy areas, Opportunity will need to stop and take a "toe dip'' -- that is, drive forward a short distance and ... more Astronauts upbeat after hard 'ballistic' landing 
Star City, Russia (AFP) April 21, 2008The first South Korean in space together with the American and a Russian who accompanied her said on Monday they were recovering well after a gruelling "ballistic" descent to Earth. Yi So-Yeon, who returned from the International Space Station (ISS) on Saturday in an irregular landing that subjected the crew to huge gravitational forces, said there had been nothing to worry about either ... more Mars Technology On Board A Balloon To Study The Earth's Atmosphere 
Kiruna, Sweden (SPX) Apr 22, 2008"From Mars to the Earth and back" is the theme when the Swedish Institute of Space Physics (IRF), the Swedish Space Corporation (SSC) and University of Bern in Switzerland build and launch a mass spectrometer on a stratospheric balloon from SSC's operational facility Esrange Space Center in Kiruna. The project is called MEAP (Mars Environment Analogue Platform) and will be carried out ... more |

Moscow (XNA) Apr 14, 2008Russia is going to create a manned assembly complex in orbit, the chief of the Federal Space Agency Anatoly Perminov said here on Saturday. "We shall create this complex in order to make dockings in orbit, build craft there and send them to the Moon, Mars and other planets," Perminov was quoted by the Itar-Tass news agency as telling a new briefing. "This proposal was on the wh ... more Russia Continues Flight Simulation Experiments For Mars-500 
Moscow (RIA Novosti) Apr 16, 2008Four volunteers will spend ten days in a compression chamber with a reduced oxygen level as preparation for Mars-500, a Russian ground-based experiment to simulate a flight to Mars. A spokesman for the Moscow-based Russian Institute of Medical and Biological Issues, which runs the project, said that four healthy men will be held in a chamber with the pressure equivalent to being five meters ... more Missions To Mars 
Paris, France (SPX) Apr 15, 2008The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. GSI was selected because its accelerator is the only one in Europe able to create ion beams similar to those found in space. To determine possible health risks of manned space flights, scientists from all over Europe have been asked to investigat ... more Opportunity Continues Reading The Story In The Rocks 
Pasadena CA (SPX) Apr 14, 2008Opportunity has finished grinding into the surface and acquiring microscopic images of a rock target informally named "Gilbert," at the bottom of the alcove inside "Victoria Crater" known as "Duck Bay." The rover is in the middle of a campaign to study the composition of the exposed interior of the rock using both the Mossbauer and alpha-particle X-ray spectrometers. Some time next week ... more |

Pasadena CA (SPX) Apr 10, 2008A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars. The High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took two images of Phobos 10 minutes apart on March 23. Scientists combined the images for a stereo view. "Phobos is of great interest because it may be rich in water ic ... more Visting Mars, Again And Again 
Mpffett Field CA (SPX) Apr 08, 2008Mars is preparing for an invasion from Earth. The rovers Spirit and Opportunity are still traveling across the surface of the Red Planet, but NASA and the European Space Agency are planning to send more missions over the next few years. First up is the Mars Phoenix lander. Launched last year, this mission is due to arrive near the Martian north pole on May 25. The lander won't be able to ... more Aerojet And Orbital Test Next Gen Safety System For NASA's Orion Program 
Sacramento CA (SPX) Apr 08, 2008Aerojet and Orbital Sciences have announced that together the two companies successfully conducted a static firing of the jettison motor, a key component of the Launch Abort System (LAS) for NASA's Orion next generation human spaceflight program. Lockheed Martin is the prime contractor for the Orion project, which is part of NASA's Constellation Program to send human explorers back to the moon ... more No Speed Limit On Mars 
Pasadena CA (SPX) Apr 07, 2008It's a good thing there's no speed limit on Mars, because the next parachute to fly to the red planet will deploy faster than you can legally drive on a California freeway! The chute is designed to slow the Mars Science Laboratory as it rockets through the Martian atmosphere at more than twice the speed of sound and places a car-size rover on the surface. At its carefully selected landing ... more
